## Abstract

The Commission adopted rules to implement section 222 of the Communications Act of 1934, as amended, which governs carriers' use and disclosure of customer proprietary network information. In this document, the Commission responds to the practice of "pretexting" by strengthening its rules to protect the privacy of customer proprietary network information (CPNI) that is collected and held by providers of communications services.
